SYSTEM OF GAS-LIGHTING.

SPECIFICATION forming m of Letters Patent no. 283,020, dated August 14, 1883.

Application filed January 10, 1883. (No model.) Patented in France July 18, 1882, No. 159,169, and in Belgium September 12, 1882,

No. 59.004. p

' 5 tem of Gas-Lighting called Pneum a-Hydrique L1ght, and I do hereby declare that the fol-' lowing is a full, clear, and exact description of the same, reference being bad to the annexed sheet of drawings, making apart of this speci- Io fication; and I furtherstate that I have received Letters Patent of France for said invention for fifteen years, dated July 18, 1882, N 0. 159,169, and Letters Patent of Belgium for fifteen years, dated September 12, 1882, No.

This invention relates to an improved burner of special construction, hereinafter described, whereby an intense and steady light resembling the electric light in whiteness and brilliancy is obtained.

In order that the invention may be more readily understood, I will proceed to describe it with reference to the accompanying drawings, which give several examples of the ar- 2 rangements of the apparatus.

Figure 1' represents an elevation, and 2 a central vertical section, of the burner which I employ. Figs. 3 and 4 are horizontal a'horizontal section of the same on line 5 6,

Fig. 5.

The same letters of reference indicate the 3 5 same parts in all the figures.

According to this invention, the supporter of combustion is mixed with the combustible gas before its arrival at the burner, the mix; ture being effected by leading a tube by which 40 air is supplied at suitable pressure into the gas-supply pipe, whereby the air-current. carries the gas along Y nd becomes mixed with it before arriving at the burner.

The burner, which may be readily adapted 5 to existing gas-fittings, is constructed as shown in Figs. 1, 2, 3, 4. It consists of a central tube, 5, screwing upon the pipe by which the gaseous mixture is supplied. Upon the'tube v3 is adjustably screweda hollow cup, k, of

metal or refractory material, which supports a cap, Z, of fire-clay, of suitable form, according to the intended use of the burner. base of this thimble-shaped cap Z is perforated with a ring of holes, m, assmall and numerous as possible, and the sides of the cap are pierced with oblique perforations n. The top of the tube z is provided with four small knobs or The flanged projections, upon which rests a copper 'or other cone, 0, soldered to said tube at apoint.

below the vertical perforations m in the base of the refractorythimble Z. The cone 0 is per forated with small holes, 1), at its lower end, the sum of whose areas is at least equal to the area of the tube. The refractory'thimble Z is surrounded by an envelope, 9, of platinum, wire-netting, or fabric, or other refractory material of the same form. The gaseous mixture, arriving by pipe 2', escapes at the upper orifices, a", and passes down against the inte-'' rior surface of the copper cone 0, out at orifices p, and escapes through the orifices in the cap Z, at which is burned. The cap is thereby raised to a high temperature, and the platinum-wire sheath, becoming incandescent, radiates the light, the gaseous mixture coming first in contact with the copper cone and then with the refractory cap, becoming raised to an exceedingly high temperature before it is consumed.

The forms and dimensions of the several parts of the burner may be varied and the cone 0 be dispensed with, according to the denumber of small perforations, r, at its upper end, the sum of whose areas is at least equal to the area of the tube, and by which the gaseous mixture is distributed within the chamber k. Upon the upper closed end of the tube is fixed a hollow cylinder, 0, of fire clay, closed at the lower and open at its npper'end; A

refractory cap, Z, surrounds the cylinder 0, and

rests by its base upon 'cup is. This flanged base is perforated with small vertical holes, m, and upon it is fixed a platinum-wire cage or envelope, 9. An annular space, i, is left between Z and 0 for the passage of the gaseousmixture, which, on escaping from the orifices "r in tube 6, passes over the exterior surface of 0, whose.

interior is already heated by the flame, which 5 has not passed through the wire-gauze and has been forced by the pressure of the mixture into the interior of 0'. The gaseous mixture, be-

fore passing through the annular. space 25, thus reaches such a temperature that on escaping 10 from this orifice its combustion is'greatly promoted. e

p The compressed air supplied to the gas-supply pipe, as above described, may be made to pass through any suitable pressure-regulator.

I claim- I 5 1. The combination of the air and gas supply pipe i with the cup 70, flanged porous cap Z, and envelope 9, of platinum, substantially as herein shown and described.

2. The combination of the air and gas sup- 2o ply pipe 6 with the cup is, flanged porous cap Z, cone 0, and envelope 9, of platinum, substan tially as herein shown and described.
